To all whom it may concern:

. of regenerative chambers, one of which is adapted to receive the products of combustion from the furnace while the opposite chamber simultaneously receives a charge. of fresh air which becomes thoroughly heated by passing through and absor ing the heat from the checker work of said chamber, each of these regenerativechambers being controlled by suitable valves to reverse the passage of the air and products of combustion and each of said chambers also communicating'with a single channel way which leads to the combustion chamber of the furnace so that the re-heated air will at all times enter the said combustion chamber and flow in a given direction and thus cause the flame to act in a constant direction.

In the accompanying drawings illustrating my invention, Figure 1 is a diagrammatic view of my invention showing the general arrangement in connection with a urnace or oven, Fig. 2 is a horizontal section of my device, Fig. 3 is'a vertical section through the coldreversing chamber and valves, Fig. 4 1s a vertical section through the hot reversing 'valves, and Fig. 5 is a vertical section through the cold reversing valves.

In my improved apparatus, the waste heat employing device is in controlled communication with' the outlet of a furnace for the products of combustion and is interposed in the course of these products to the stack.

It is in communication with the supply of air to the device through the furnace. The apparatus for using the waste comprises a series of communicat'png chambers containing checker-work 'of re brick and separately controlled. This checker-work is intensely heated by the Waste products of combustion admitted to the several 'cham-. bers alternatelyand the temperature of said roducts is considerably reduced on reach mg the stack, by which means undue heatingv of thestack is prevented. When one chamber has become unduly heated communication between the furnace and stack is opened through another similar chamber of checker-work and the first process is repeated. The chamber already heated is opened to the air which circulates from the Patented Nov. 26, 1912.

coldest part of the regenerator to its hottest part and is heated on its way to the combustion chamber ,by the employment of counter currents.

The following is a description of my improved .device' A is a furnace hearth, B is the combustion chamber, D and E are the chambers of checker-work, F is the flue leading from the furnace to the chambers.

M and K are ports leading from the chambers to the hot air chamber L H and -N are similar ports adapted to direct the flow of the waste, heat from the flue F through the cold chamber.

O and P are double acting valves adapted to open and close the first and second sets of ports alternately and externally controlled at O and P Q and Q are openings between the port openings and the respective checker-work chambers.

S and S are ports of the chambers communicating both with the inlet S, for admission of cold air and with the'stacln T is the cold air and waste gas reversing valve: I

V is the entrance to the stack.

Air is supplied tothe combustion chamber B from the hot air chamber L, admitted from without through the port S and passing through the checker chambers E and D alternately from ports S and S controlled by valve T. Admission into the hot air chamber L is controlled by ports M and K while ports H and N make the connections between the flue F and the chambers and are closed or opened in alternate pairs as shown in Fig. 4 one interior and one exterior port comprising the respective pairs. -With the ports M and N opened, air from the checker-work chamber E flows through the passage Q and through port M to the hot air chamber L and from thence to the combustion chamber B. Hot waste gas from the hearth A passes down the flue F into the port N through the passage Q and thence through chamber D heating the checkers/ori Having given. up cart of J lv heat it passes to the stack through the port When chamber D has been 'suiiicientiv heated, the reversal of the valves 0, P and T reverses the course of the air and the hot gases from one of the checker work chambers to the other the supply to the hot air chamber L now proceeding from the chamber D and. through the port- K. The closing; of port N shuts off the hot air from the fur nace from chamber l) and it proceeds through port 111 to chamber E. The reverse of valve T opens port S to the air and closes port S which now conducts the gases from chamber E to the stack V The advantages elf-my device consist essentially' in the fact that aii products of combustion must pass through the regenerating checker-Work chambers and the inoo-m ing air flows from the coldest port of the regeneratorto its hottest port The i a that the valves 0 and P are always hot and in contact with hot gases tends lnateriaii to diminish the loss of heat sustained by a valve which is aiternately cold and hot such as have been heretofore employed.

In combination with a furnace, a regenerating apparatus, interposed between the :turnace and its smoke stack; saia apparatus being provided with two independent re 4 berating chambers having checkered inner "ills; vaive chamber adjacent tile furnace tor each regenerating chamber; a port bei tween each valvevchamber and its regenerating chamber; a passage from each valve 1 chamber to the combustion chamber of the r furnace; a second passage from each valve 1 chamber to the waste gas flue of the furnace; I an inter-communicating passage between saicl second passages; aswing valve in each valve chamber adapted to close the one while opening the other of either of said passe of the valve chamber; a valve housing adjacent the smoke stack common to both regenerating chambers; an air inlet port in said housing; a port for each of said t reg aerating chambers in said housing; a n said housing leading to the smoke in a valve in said housing adapted to v e communication between the .atmos: re and one of said regenerating chamwhile simultaneously making commu nication between the other regenerating chamoer and the smoke-stack.
